[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] like Figures 1 to 3 As shown, an easily replaceable lamp according to an embodiment of the present invention includes: a base 200 and a lamp body; the base 200 has a plug hole 211, and a connection terminal 215 is provided in the plug hole 211; the lamp body is provided with a fastener 120, a lamp holder 130 and a light-emitting element 140, the light-emitting element 140 is disposed on the lamp holder 130, the lamp holder 130 is provided with a first pin 131, the light-emitting element 140 is provided with a second pin 141, the first pin 131 is connected to the second pin 141, the first pin 131 is plugged into the plug hole 211 so that the second pin 141 abuts against the connection terminal 215, and the fastener 120 is fastened to the base 200 so that the lamp body is mounted on the base 200.

[0025] Align the first pin 131 with the connector hole 211 and insert the first pin 131 into the connector hole 211, so that the second pin 141 abuts against the connecting terminal 215. The light-emitting element 140 abuts against the connecting terminal 215 through the second pin 141, realizing the conduction of the light-emitting element 140 to the external power supply. Then, fasten it to the base 200 with the fastener 120, and the lamp body can be installed on the base 200. The installation is simple, convenient and quick, improving assembly efficiency. Loosen the fastener 120 from the base 200, and the lamp holder 130 can be pulled out from the base 200 to complete the separation and disassembly of the lamp body. The operation is simple. The lamp body and the base 200 are detachably assembled together. When the lamp body is damaged, it is convenient to replace the lamp body, reducing the difficulty of lamp repair, reducing maintenance costs, and improving user experience.

[0026] Understandably, referring to Figure 1 , Figure 4 and Figure 5 The base 200 has a positioning hole 212, and the lamp holder 130 has a positioning block 136. The positioning block 136 matches the positioning hole 212 and is inserted into the positioning hole 212. There are at least two insertion holes 211. The connection terminals 215 of the insertion holes 211 are respectively connected to the positive and negative poles of the external power supply. By setting the positioning hole 212, the positioning block 136 is inserted into the positioning hole 212, so that the first pin 131 can be accurately inserted into the corresponding insertion hole 211, avoiding the positive and negative poles of the light-emitting element 140 being reversed with the positive and negative poles of the external power supply, protecting the light-emitting element 140 and reducing safety risks.

[0027] Understandably, referring to Figure 2 and Figure 4 The lamp holder 130 has a mounting hole 134. A second pin 141 passes through the mounting hole 134 and connects with the first pin 131 to position the light-emitting element 140 within the mounting hole 134. By connecting the second pin 141 through the mounting hole 134 and the first pin 131, the second pin 141 moves the light-emitting element 140 into the mounting hole 134, thus initially positioning the light-emitting element 140 on the lamp holder 130.

[0028] Specifically, refer to Figure 2 and Figure 4The mounting hole 134 has a protruding support portion 133 on its sidewall. The end of the second pin 141 is provided with a barb portion 142, which engages with the end of the first pin 131. At the same time, the light-emitting element 140 abuts against the support portion 133. By engaging the lower end of the first pin 131 with the barb portion 142 on the second pin 141, the light-emitting element 140 is driven to fit tightly against the support portion 133, and the light-emitting element 140 is positioned axially. At the same time, the sidewall of the mounting hole 134 positions the light-emitting element 140 radially, further stabilizing the light-emitting element 140 on the lamp holder 130, reducing the risk of damage to the light-emitting element 140, reducing the shaking of the light-emitting element 140, reducing abnormal noise after assembly, and improving the user experience. Furthermore, by engaging the lower end of the first pin 131 with the barb 142, when the first pin 131 is inserted into the socket 211, the anti-interference capability of the second pin 141 is enhanced, preventing the second pin 141 from shifting under force during the insertion of the first pin 131 into the socket 211, thus avoiding poor contact between the second pin 141 and the connecting terminal 215 and ensuring stable circuit connection.

[0029] Understandably, referring to Figure 2 and Figure 4 The first pin 131 has a limiting groove 135, which matches the barb portion 142, which is disposed within the limiting groove 135. When the barb portion 142 is engaged with the end of the first pin 131, the barb portion 142 is placed within the limiting groove 135, reducing the offset of the barb portion 142, further ensuring the connection stability between the barb portion 142 and the first pin 131, and further enhancing the anti-interference capability of the second pin 141, so that the second pin 141 is stably connected to the connecting terminal 215.

[0030] Understandably, referring to Figure 2 and Figure 5 Fastener 120 is fitted onto lamp holder 130. Base 200 has a protruding connecting part 210 that matches fastener 120. Insertion hole 211 is formed on connecting part 210. When lamp holder 130 and base 200 are inserted into each other, fastener 120 and connecting part 210 are securely connected. The protruding connecting part 210 facilitates alignment of the lamp assembly with base 200. After the lamp assembly is inserted into connecting part 210, fastener 120 is then securely connected to connecting part 210, allowing lamp holder 130 to be installed onto base 200, thus improving assembly efficiency.

[0031] Specifically, refer to Figure 2 and Figure 3The base 200 has a clearance hole 220. A third snap-fit ​​part 221 protrudes from the inner wall of the clearance hole. The third snap-fit ​​part 221 is located at the end of the clearance hole 220 near the lamp holder 130. A fourth snap-fit ​​part 214 protrudes from the outer side of the connecting part 210. The connecting part 210 is fitted into the clearance hole 220. The connecting part 210 protrudes from one end of the base 200. The third snap-fit ​​part 221 and the fourth snap-fit ​​part 214 are snapped together. A sealing ring 213 is fitted onto the outer side of the connecting part 210. The sealing ring 213 abuts against the third snap-fit ​​part 221. By setting the sealing ring 213, when the fastener 120 is securely connected to the connecting part 210, the fastener 120 and the third snap-fit ​​part 221 cooperate to compress the sealing ring 213, making the sealing ring 213 tightly adhere to the third snap-fit ​​part 221, the connecting part 210, and the fastener 120, thereby enhancing the waterproof performance of the lamp body and making the lamp body suitable for outdoor use, thus improving its practicality. The fourth snap-fit ​​part 214 and the sealing ring 213 abut against the two sides of the third snap-fit ​​part 221, respectively. The fastener 120 is securely connected to the connecting part 210 and abuts against the base 200. With the fourth snap-fit ​​part 214 abutting against the third snap-fit ​​part 221, the connecting part 210 and the base 200 are stably assembled together.

[0032] It is understandable that the lamp body and the connector are electrically connected by a wire. One end of the wire extends into the clearance hole 220 and connects to the connection terminal 215. A partition plate is provided in the clearance hole 220. The partition plate is placed between the wires to separate them, prevent short circuits caused by damage to the outer layer of the wires, and improve service life.

[0033] Reference Figure 2 In the first embodiment where the fastener 120 is connected to the base 200, the fastener 120 is rotatably mounted on the lamp holder 130 and threadedly connected to the connecting part 210. A insertion hole 211 is provided on the connecting part 210. After the first pin 131 is inserted into the insertion hole 211, rotating the fastener 120 causes it to be threadedly connected to the connecting part 210, thus installing the lamp assembly onto the base 200 and ensuring the stability of the connection between the lamp holder 130 and the base 200. During disassembly, rotating the fastener 120 allows the lamp holder 130 to be separated from the base 200, simplifying disassembly and saving time.

[0034] Reference Figure 3In a second embodiment of the connection between the fastener 120 and the base 200, in some other embodiments of this utility model, the fastener 120 is sleeved with the connecting part 210. A locking block 123 is provided on the inner side of the fastener 120, and a first locking groove is provided on the outer side of the connecting part 210. The locking block 123 engages in the first locking groove. After the first pin 131 is inserted into the insertion hole 211, the fastener 120 is driven to engage the locking block 123 with the first locking groove, locking the lamp holder 130 onto the base 200. This ensures a stable connection between the lamp holder 130 and the base 200, which is convenient, quick, simple, and effective. Furthermore, during disassembly, by driving the lamp body to move axially, the fastener 120 is moved axially, causing the locking block 123 to disengage from the first locking groove, simplifying disassembly and improving efficiency.

[0035] Understandably, referring to Figure 2 or Figure 3 The lamp body also includes a cover 110, which is fitted onto a lamp holder 130. A limiting portion 132 protrudes from the outer side of the lamp holder 130. The lower end of the cover 110 abuts against the limiting portion 132. A fastener 120 is fitted onto the outer side of the lamp holder 130, and the fastener 120 is securely connected to the cover 110, thus positioning the lamp holder 130. A light-emitting element 140 is placed inside the cover 110, which protects it, allowing the decorative lamp to be used outdoors. The cover 110 can be set to any color and any transparency, allowing the light-emitting element 140 to emit light of different colors and effects through the cover 110, creating different atmospheres, enriching the functionality of the decorative lamp, and enhancing the user experience. Furthermore, the fastener 120 assembles the cover 110 and the lamp holder 130 together, making the overall structure of the lamp body compact and enhancing its structural strength.

[0036] Understandably, referring to Figure 2 or Figure 3The inner wall of the fastener 120 protrudes to form a first snap-fit ​​portion 121 and a second snap-fit ​​portion 122. The first snap-fit ​​portion 121 and the second snap-fit ​​portion 122 are arranged sequentially along the axial direction. The cover 110 has a second slot 111. The first snap-fit ​​portion 121 snaps into the second slot 111, and the second snap-fit ​​portion 122 snaps into the limiting portion 132. The limiting portion 132 is located between the first snap-fit ​​portion 121 and the second snap-fit ​​portion 122. During assembly, the lamp holder 130 is first sleeved with the fastener 120, so that the limiting part 132 abuts against the upper part of the second snap-fit ​​part 122. Then, the cover 110 is inserted into the fastener 120 from the top, so that the first snap-fit ​​part 121 snaps against the second snap-fit ​​groove 111, connecting the cover 110 and the fastener 120 together. Then, the end of the cover 110 abuts against the limiting part 132 and cooperates with the second snap-fit ​​part 122 to assemble the cover 110 and the lamp holder 130 together, making the overall structure of the lamp body compact, enhancing the structural strength of the lamp body, and facilitating automated assembly, thus improving assembly efficiency.

[0037] This utility model provides a convenient replacement lamp.
